IMPROVEMENT IN DUMPING-WAGONS.

Specification forming part of Letters Patent No. 135,195, dated January28, 1873.

- full and true description thereof, reference being had to theaccompanying drawing and to the letters of reference marked thereon.

This invention relates to four-wheel dumping-wagons, adapted for use forexcavations,

coal-yards, mines, railway works, canals, brickyards, &o. The object ofthe improvements here presented is to facilitate the dumping or tiltingof the wagon-bed by rendering the same self-operatin g, and also at thesame time which shall open and close its tail-board. The nature of thisinvention consists in the construction and combination of the variousparts with a wagon-bed, to operate as hereinafter will more fullyappear.

To enable those herein skilled to make anduse my said invention, I willnow more fully describe the same, referring to Figure 1 as a perspectiveview; to Fig. 2 as a side elevation, showing wagon-bed in closedposition; to Fig. 3 as a detail section of subaxle.

A is the wagon-bed; B, the front and B hind wheels. The front wheels Bare supported in proper axle b. The front axle b is provided withturn-table parts 12 b and crosstree b the said parts being constructedand operating as ordinary. In order to position the hind wheels 13 in amore forward position than usual, and also to support the wagonbed so asto tilt on a point within the circle described by said hind wheels, Ihave constructed the frame attachment as follows: My improved frameattachment consists of the main-frame supports 0 C of the angularconstructive form clearly shown in Figs. 1 and 2. The main frames 0 Oare arranged both sides of the wagon-bed A, the front part resting andbeing properly secured to cross-tree I), while to the rear of saidsupports 0 G are secured sub-axles c, which support the hind wheels B,as illustrated in Fig.1 and 2 and 3. The angular constructive formvofthe mainsupport frames 0 0 enables me to support and tilt the wagon-bedA on a cross-shaft, 0 arranged to pass centrally through the side beamsof said wagon-bed. (See Fig. 1.) The wagon-bed is thus most equallybalanced, readily tilted, and the forward position of the hind wheelsenables same to sustain the greater part of the weight. To the mainframes 0 C are further united, at 0 0 an angle truss or brace, D, theobject whereof being to strengthen, brace, and secure said main framestogether by the cross-shaft d, as shown in Fig. 1 and 2. Further, to themain frames (3 O are bolted, at e 6, two supporting-arms, E E,'whichextend backward to the rear of wagon-bed A, and are of the constructiveform clearly shown in Figs. 1 and 2. F is the tail-board. The tail-boardF,'instead of being slid in between cleats secured to the sides of thewagon-bed A, as ordinary, is properly hinged, at f, to the twosupportingarms E E. By removing one of the pins the tail-board can bemade to swing on one of the hinges, or entirely taken from wagon-bed bywithdrawing both pins out of the hinges. The tailboard F being leftsecured to the supportingarms E E, the tilting action of the wagon-bedself-opens to unload and closes to load.

In order to better accomplish the opening and-closin g action of thewagon-bed, the side boards of same, at their rear ends, are formedinclined, so as to fit and close in the end mortises f of thetail-board. (See Figs. 1 and 2.) The driver or operator is thus notnecessi tated to leave his seat to remove and replace the tail-board.

The frame attachment aforesaid constitutes a substantial portion of thewhole wagon, gives great strength and steadiness to all its parts, andat same time admits of abundant space for the bed to drop to fullrequired vertical position when unloading its load.

G is a catch or hook bolted to rear part of supporting-arms E E, saidhooks being to brace and steady the rear parts of wagon from undueweight brought to bear upon said point.

Having thus fully described my said improvements, what I claim is- Therear supporting-arms E E, tail-board F, catch G, angle-braceD,connecting-shaft cl, main supports 0 O tilting-shaft 0 when arranged tooperate in combination with a wagon-bed, A, and wheels B B, as and forthe purpose set forth.

In testimony of said invention I hereunto set my hand.
